This is a follow-up study of 96 patients with pineal tumors, except for one patient who was lost to follow-up. 60 of these tumors were verified histologically either at operation or at necropsy, 6 were diagnosed by epitheloid cells existing in the cerebrospinal fluid, and 30 were diagnosed by clinical and ventriculographic findings. In agreement with Russell and Rubinstein, we have classified the histologically verified tumors into 3 groups, as follows; 1. True
Pinealoma
Group (Pineocytoma, Pineoblastoma), 2. Germinoma-Teratoma Group, 3. Others (
Glioma
, Cyst). The following points need to be emphasized in the planning of management: 1.
Pinealoma
(Two cell pattern pinealoma) responds favorably to radiation therapy. 18 of 43 patients of pinealomas who were treated with irradiation are functioning normally in various life situations for more than 5 years. Among them, 5 cases of pinealomas treated with irradiation alone have more than 10 years survivals. 2. There is a limitation in the efficacy of irradiation therapy in cases of spinal cord implantation, infiltration in adjacent structures or subependymal infiltration along the ventricular cavity. 3. Only 2 of 67 patients with pinealomas had spinal cord metastasis. It seems undesirable to subject all patients to complete cerebrospinal axis irradiation. 4. Successful removal were performed in 4 patients with teratomas and are now alive for 9-21 years. None of them, however, are doing well clinically with many neurological deficits. 5. Since adenocarcinoma, teratocarcinoma, teratoblastoma and others are not sensitive to radiation therapy, only the palliative treatments are available. 6. Therefore, the most promising treatments for pineal tumors is that irradiation, plus shunting operation when required, is a first choice and after irradiation, radical removal should be tried in the case of teratoma diagnosed by clinical and ventriculographic findings.

The authors report a rare case of tuberous sclerosis associated with pineal region mixed
glioma
. A 38-year-old woman with tuberous sclerosis, who had a past history of left nephrectomy and tumorectomy of the right kidney for bilateral renal angiomyolipomas, was admitted because of headache and ataxic gait. CT scan and cerebral angiography suggested a
pineal region tumor
. Suboccipital craniectomy and partial removal of the tumor was performed via infratentorial supracerebellar approach. Microscopic examination revealed mixed oligodendroglioma and astrocytoma. It is well known that tuberous sclerosis is occasionally associated with brain tumors. However, with few exceptions, these have been subependymal giant cell astrocytomas in the lateral ventricles. They seem to originate from subependymal nodules of hamartomatous nature. As far as we are aware, association of
pineal region tumor
with tuberous sclerosis as in this case has not been reported.

The papillary tumor of the pineal region (PTPR) is a distinct entity that is particularly rare in the pediatric population. The authors document the youngest reported patient with this clinicopathological entity to date. A case of PTPR in a 15-month-old boy is described. Initially thought to be a tectal
glioma
, the tumor was later identified as a
pineal region tumor
after demonstrating growth on routine imaging. Diagnosis of PTPR was established by histopathological evaluation of biopsy samples, which revealed papillary, cystic, and solid tumor components. The patient's postoperative course was complicated by tumor growth despite several debulking procedures and chemotherapy, as well as persistent hydrocephalus requiring 2 endoscopic third ventriculostomies and eventual ventriculoperitoneal shunt placement. After a 15-month follow-up period, the patient has received proton-beam therapy and has a stable tumor size. The PTPR is a recently described tumor of the CNS that must be included in the differential diagnosis of pineal region masses. The biological behavior, prognosis, and appropriate treatment of PTPR have yet to be fully defined.

OBJECTIVE Indocyanine green videoangiography (ICG-VA) is an intraoperative technique used to highlight vessels in neurovascular surgery. Its application in the study of the vascular pathophysiology in CNS tumors and its role in their surgical management are still rather limited. A recent innovation of ICG-VA (i.e., the FLOW 800 algorithm integrated in the surgical microscope) allows a semiquantitative evaluation of cerebral blood flow. The aim of this study was to evaluate for the first time the systematic application of ICG-VA and FLOW 800 analysis during surgical removal of CNS tumors. METHODS Between May 2011 and December 2017, all cases in which ICG-VA and FLOW 800 analysis were used at least one time before, during, or after the tumor resection, and in which surgical videos were available, were retrospectively reviewed. Results of the histological analysis were analyzed together with the intraoperative ICG-VA with FLOW 800 in order to investigate the tumor-related videoangiographic features. RESULTS Seventy-one patients who underwent surgery for cerebral and spinal tumors were intraoperatively analyzed using ICG-VA with FLOW 800, either before or after tumor resection, for a total of 93 videoangiographic studies. The histological diagnosis was meningioma in 25 cases,
glioma
in 14, metastasis in 7,
pineal region tumor
in 5, hemangioblastoma in 4, chordoma in 3, and other histological types in 13 cases. The authors identified 4 possible applications of ICG-VA and FLOW 800 in CNS tumor surgery: extradural surveys allowed exploration of sinus patency and the course of veins before dural opening; preresection surveys helped in identifying pathological vascularization (arteriovenous fistulas and neo-angiogenesis) and regional venous outflow, and in performing temporary venous clipping tests, when necessary; postresection surveys were conducted to evaluate arterial and venous patency and parenchymal perfusion after tumor removal; and a premyelotomy survey was conducted in intramedullary tumors to highlight the posterior median sulcus. CONCLUSIONS The authors found ICG-VA with FLOW 800 to be a useful method to monitor blood flow in the exposed vessels and parenchyma during microsurgical removal of CNS tumors in selected cases. In particular, a preresection survey provides useful information about pathophysiological changes of brain vasculature related to the tumor and aids in the individuation of helpful landmarks for the surgical approach, and the postresection survey helps to prevent potential complications associated with the resection (such as local hypoperfusion or venous infarction).
